Using hospital medical record data to assess the accuracy of the SEER Los Angeles Cancer Surveillance Program for initial treatment of prostate cancer: a small pilot study

Purpose Treatment information from the Surveillance, Epidemiology, and End Result Program (SEER) cancer registries is increasingly being used for population-based cancer research; however, it may be incomplete for outpatient procedures and is not quality controlled. We sought to validate SEER information on initial treatment of prostate cancer by comparison to electronic medical record (EMR) review.
